Question
A nonconducting sphere with uniform charge density has a radius a and a total charge +2q; a nonconducting spherical shell (with uniform charge density) has an inner radius b, outer radius c, and total charge −q.
Find expressions for the electric field in the regions (a) r < a, (b) a < r < b, (c) b < r < c, and (d) r > c.
For parts (e) through (h), now assume the sphere and shell are conductors, though with their net charges unchanged; find expressions for the electric field in the regions (e) r < a, (f) a < r < b, (g) b < r < c, and (h) r > c.
